Synthesis of long-chain polyketide fragments by reaction of 1,3-dioxy-1,3-dienes with allylsilanes: Umpolung with sulfur dioxide
2004
In the presence of a Lewis or protic acid and at low temperature, 1,3-dioxy-1,3-dienes add to sulfur dioxide generating zwitterionic intermediates that can react with carbon nucleophiles such as allylsilanes. After a retro-ene elimination of SO2, valuable polyketide precursors are obtained.
